Postdoc position in Efficient NLP for Information Extraction from News

This 24-month postdoctoral position is a close collaboration between the National Police Lab AI (Floris Bex and Jelte Mense) and the Natural Language Processing Group (Albert Gatt) at Utrecht University. Together, we want to explore how small models can extract useful information on specific crime themes, such as drug trafficking, primarily from publicly available news sources. Relevant tasks include identifying relevant entities (who did what, where), and inferring timelines (when, and in what order) and relations (e.g. links to specific countries or groups). A promising direction is to train or fine-tune small-scale models via distillation from larger models, including through the use of synthetic data. This in turn raises interesting questions about the robustness of the resulting models, their ability to generalise, and their susceptibility to known issues related to synthetic data training, such as model collapse.

As a postdoctoral researcher on this project, you will:

• Design and evaluate methods for multimodal entity, timeline and relation extraction from multilingual news sources.
• Fine-tune and distil small-scale language models from larger models, including via synthetic data generation.
• Investigate the robustness, generalisability and limitations (e.g. model collapse) of the resulting models.
• Apply and validate the approach on real-world use cases, such as drug trafficking, together with the Netherlands police.
• Publish and present your findings at relevant conferences and in scientific journals., In addition to the terms of employment laid down in the CAO NU, Utrecht University also offers a range of its own schemes for employees. This includes arrangements for professional development, various types of leave, and options for sports and cultural activities. You can also tailor your employment conditions through our Terms of Employment Options Model. In this way, we encourage you to keep investing in your personal and professional development.

We are excited to welcome an enthusiastic new colleague who thrives in an interdisciplinary and international team and meets the following criteria:

• A PhD (obtained, or nearly completed) in Natural Language Processing or a closely related area.
• Solid knowledge of machine learning, especially deep learning.
• Experience in model development and/or fine-tuning.
• A practical mindset - interested in seeing your models used, not just published.
• Fluency in spoken and written English (C1 level). Good knowledge of Dutch is an asset, though not required, to facilitate collaboration with the Netherlands Police.

• a full-time position for 24 months;
• a permanent employment contract;
• a gross monthly salary between € 3.706 and €5.760 based on full-time employment (salary scale 10 under the Collective Labour Agreement for Dutch Universities (CAO NU));
• 8% holiday pay and 8.3% year-end bonus;
• a pension scheme, partially paid parental leave and flexible terms of employment based on the CAO NU.
